Description

Technical Field

[0001] This utility model relates to the field of power bank technology, and in particular to a split-type power bank. Background Technology

[0002] A wireless power bank is a portable energy storage device that charges electronic devices wirelessly, eliminating the need to carry or plug and unplug data cables, thus offering high convenience. However, current wireless power bank designs have certain limitations, as follows: On the one hand, some wireless power banks, in pursuit of ultimate portability and cost control, only support wireless charging themselves. This means they cannot power devices that do not support wireless charging, limiting their application range. On the other hand, even if some wireless power banks support wired charging, they generally adopt an integrated design of battery and casing, resulting in a small and compact internal space. This structure makes it difficult to install an efficient heat dissipation system, thus limiting the maximum power of wireless charging. Furthermore, the non-separable design of the battery and casing means that if the power bank malfunctions, users often cannot easily detect the cause of the malfunction. Therefore, for convenience, users often simply discard the damaged power bank and buy a new one, which not only increases the user's cost but also creates unnecessary electronic waste.

Detailed Implementation

[0030] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings. Example 1

[0031] like Figures 1 to 5 The first embodiment of the present invention is a split-type power bank, which includes a bottom shell 1 and a cover 21 disposed on the bottom shell 1. The bottom shell 1 and the cover 21 are fixedly connected by a buckle to form a receiving chamber. The battery is removably disposed in the receiving chamber. A PCB main board 41 is also fixedly disposed in the receiving chamber by screws. The PCB main board 41 is provided with a connecting device for fixing the battery so as to realize the detachable connection between the battery and the shell.

[0032] The cover 21 has a guide groove 211 on one side, and the battery has a strip-shaped protrusion 311 that matches the guide groove 211. The battery has a charging interface, which can be a Type-C interface. Of course, in other embodiments, the charging interface can also be a Micro-USB, Lightning, etc.

[0033] In addition, the battery is the first battery 31, and the charging interface is the first charging interface 312.

[0034] The connecting device includes a magnetic charging plug 5 disposed on the PCB motherboard 41. When the magnetic charging plug 5 is magnetically connected to the first charging interface 312, the magnetic charging plug 5 attracts and fixes the first battery 31 in the receiving cavity. The conductive contacts of the magnetic charging plug 5 form a tight electrical contact with the first charging interface 312. The interface form of the magnetic charging plug 5 is adapted to the charging interface and is a Type-C plug. Of course, in other embodiments, the magnetic charging plug 5 can also be a Micro-USB plug, a Lightning plug, etc.

[0035] In addition, the PCB motherboard 41 is also equipped with a switch 42, a power indicator 43, and a third charging interface 44. The bottom shell 1 is also fixed with a partition plate 10 and a wireless charging module 11 by screws. The partition plate 10 is used to place the battery and separate it from the wireless charging module 11. An 8mm gap is reserved between the partition plate 10 and the wireless charging module 11. The wireless charging module 11 is connected to the PCB motherboard 41 by wires. The cover 21 is also equipped with a light-transmitting plate 22 by a snap-fit. The switch 42 is used to control the battery to supply power to the wireless charging module 11 through the PCB motherboard 41. The light-transmitting plate 22 is located above the power indicator 43 so that the user can observe the remaining battery power displayed on the power indicator 43 through the light-transmitting plate 22. The third charging interface 44 is a Type-C interface. It should be noted that the Type-C interface is only a preferred option and not a restrictive requirement. Other interfaces that can provide power are also feasible.

[0036] Specific working principle: When wireless charging is needed, the user can place the electronic device directly on the wireless charging module 11 of this power bank, and then press the switch 42. The current output by the battery will then pass through the magnetic charging plug 5, the PCB motherboard 41 and the wireless charging module 11 in sequence to achieve wireless charging of the electronic device. When the electronic device does not support wireless charging, the user can pull the protrusion 311 with appropriate force to pull the battery out of the housing chamber. Then the user can directly insert the charging cable into the charging interface to charge the electronic device.

[0037] When the battery needs to be returned to its place, the user first places the side of the battery with the protrusion 311 towards the guide groove 211. The guide groove 211 is used to guide the user to the correct direction of inserting the battery and also serves to prevent mistaken insertion, thus avoiding damage to the magnetic charging plug 5 caused by the user forcibly inserting the battery into the housing. Then, the battery is pushed back into the receiving cavity until the magnetic charging plug 5 is fully inserted into the charging interface. The magnetic charging plug 5 is provided with a strong magnetic piece, and the charging interface is provided with a metal piece. Through the magnetic attraction between the magnetic piece and the metal piece, and the limiting structure at the connection between the magnetic charging plug 5 and the charging interface, the battery is stably fixed in the receiving cavity. When the battery needs to be charged, the user inserts the charging cable into the third charging interface 44. The current from the data cable then flows sequentially through the third charging interface 44, the PCB motherboard 41, and the magnetic charging plug 5 before finally flowing into the battery, thus charging the battery.

[0038] The separator 10 is used to separate the battery from the wireless charging module 11. This helps the heat from the battery and the wireless charging module 11 to dissipate better during operation and avoids the heat from the two components accumulating and causing the internal temperature of the casing to become too high. Secondly, the 8mm gap between the separator 10 and the wireless charging module 11 provides ample space for the installation of an efficient heat dissipation system, allowing manufacturers to install a wireless charging module 11 with a higher charging power to improve the wireless charging power.

[0039] This achieves the following effects: By adopting a separate battery and casing design, this magnetic power bank is compatible with various electronic devices, even those that do not support wireless charging. Furthermore, it allows for a larger space to accommodate the wireless charging module 11, facilitating a better heat dissipation design and increasing the charging power of the wireless charging module 11 to meet users' strong demand for fast charging. The modular design also effectively reduces usage costs; if either the casing or the battery is damaged, only the damaged part needs to be replaced for continued use. Example 2

[0040] like Figures 6 to 11 The following is a second embodiment of the split-type power bank of the present invention. This embodiment is similar to the first embodiment, except that the battery is a second battery 32, the charging interface is a second charging interface 321, and the second battery 32 is provided with a power indicator light 322. The power indicator light 322 is used to display the power of the second battery 32, so that when the second battery 32 is pulled out of the casing, the remaining power of the second battery 32 can be known without relying on the power display 43.

[0041] The connecting device includes a base 61 fixedly mounted on the PCB motherboard 41, a locking hook 62 slidably connected to the base 61, a first spring 64 connected between the locking hook 62 and the base 61, a guide plate 65 fixedly mounted on the cover 21, the locking hook 62 slidably connected to the guide plate 65, and a locking hole 63 adapted to the locking hook 62 on the second battery 32. When the locking hook 62 is engaged in the locking hole 63, the locking hook 62 stably fixes the second battery 32 in the receiving cavity.

[0042] In addition, a power supply device is provided on the PCB motherboard 41 and the second battery 32.

[0043] The power supply device includes two first electrode plates 71 fixedly disposed on the second battery 32, and two electric needles 72 fixedly disposed on the PCB motherboard 41. The electric needles 72 are respectively connected to the first electrode plates 71 one by one to form a tight electrical contact. One first electrode plate 71 is the positive electrode and the other first electrode plate 71 is the negative electrode. The second battery 32 supplies power to the wireless charging module 11 through the electrical contact between the electric needles 72 and the first electrode plates 71.

[0044] In a preferred embodiment, when the second battery 32 needs to be removed from the housing, the user first pushes the locking hook 62 towards the base 61. During the movement of the locking hook 62, the first spring 64 is compressed. After the locking hook 62 is completely separated from the locking hole 63, the user can pull the second battery 32 out of the housing through the protrusion 311. After the user stops pressing the locking hook 62, the first spring 64 pushes the locking hook 62 to reset. When the second battery 32 is reset, the locking hook 62 is locked into the locking hole 63 again. The first spring 64 is used to support the locking hook 62 so that it is always located in the locking hole 63, so as to fix the battery more stably and firmly in the housing.

[0045] When the second battery 32 needs to be charged, the user inserts the charging cable into the third charging port 44. The current from the data cable then flows through the third charging port 44, the PCB motherboard 41 and the charging pin 72 in sequence, and finally flows into the second battery 32 through the first electrode plate 71, thereby charging the second battery 32. Example 3

[0046] like Figures 12 to 14The image shows a third embodiment of a split-type power bank according to this utility model. This embodiment is similar to the first embodiment, except that the power supply device includes two second electrode plates 95 fixedly disposed on the second battery 32, two conductive blocks 91 fixedly disposed on the PCB main board 41, and three guide rods 92 disposed on the conductive blocks 91. The guide rods 92 are made of conductive metal, and metal pins 93 are slidably connected inside the guide rods 92, thus dividing the six metal pins 93 into two groups. A second spring 94 connects the metal pins 93 and the guide rods 92, and the metal pins 93 are connected to the second electrode plates 95 to form a tight electrical contact. One second electrode plate 95 is the positive electrode, and the other second electrode plate 95 is the negative electrode. The second battery 32 supplies power to the wireless charging module 11 through electrical contact between the second electrode plates 95 and two sets of metal pins 93. A single second spring 94 can provide a thrust of 200g. Six second springs 94 are used to push the second battery 32 partially out of the housing. Of course, in other embodiments, springs with greater thrust can be selected to reduce the number of springs. It should be noted that the number of springs is only a preferred option and not a limiting requirement. As long as the thrust generated by the springs can push the second battery 32 partially out of the housing, it is also feasible.

[0047] In a preferred embodiment, when the second battery 32 is located inside the housing, the second electrode plate 95 pushes the metal pin 93 to move closer to the conductive block 91, and the second spring 94 is compressed. When charging the second battery 32, the current from the data line passes sequentially through the third charging interface 44, the PCB motherboard 41, the conductive block 91, the guide rod 92 and the metal pin 93, and finally flows into the second battery 32 through the second electrode plate 95, thereby charging the second battery 32.

[0048] When the locking hook 62 separates from the locking hole 63, the six compressed second springs 94 push the metal pin 93 to reset, and then the metal pin 93 pushes the second electrode plate 95 and the second battery 32 to move, so that the second battery 32 partially slides out of the housing, making it easier for the user to pull the second battery 32 out of the housing.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
